摘要
研究基于多声呐基阵的无源时差定位方法,从测时差定位原理入手,对定位误差与布阵几何的关系进行了分析,提出声呐基阵的最优布阵原则,对各布阵形式的定位精度进行仿真实验,给出最优布阵形式,仿真结果表明,该布阵形式在无源定位系统中有很好的应用价值。
The location method for passive time difference of arrival （TDOA） based on multiple sonar array was studied. Starting with the TDOA location principle, We analyzed the relation between position error and distribution geometry, and put forward the optimal distribution principle. The location precision of every array distribution was simulated to obtain optimal array distribution. The simulated result shows that the optimal array distribution has greatly applied value in the passive location system.
